The diversity of research approaches applied to GPCRs translates into a large diversity of affiliation of research teams working in this field. Indeed, teams of the present GDR are affiliated to many different French research organizations (CNRS, INSERM, INRA, CEA, 13 Universities). Under these circumstances, coordination appears necessary for optimal usage of available sources. The GDR3545 will represent the GPCR field in France and provide advice in any possible relevant matter at the highest level (Ministries, ANR, ITMO, etc.).
